I seem to have the feeling that people who listen to kpop go more for the looks of the artistes than the music itself...maybe I'm just biased, but that's what I infer from how people rattle on and on about how which girl in SNSD is cuter/hotter etc.
Personally I listen to all sorts of music as long as I like it when I hear it or it makes me feel good. I don't care if others think the tune / lyrics / melody etc sucks. Music is for my entertainment (hey no pun intended there even though I like that song) and pleasure, so if I think it's nice, I'll listen to it. Regardless of genre / artiste / origin. So you'll see lots of stuff in my music library...rock, metal, pop, R&B, alternative, drum and bass, etc
